Hi,
I have to install a two nodes cluster-gateway managing SSH and iptables. It
would be great if sessions could not be destroyed when a service get down.
Are there now possibilities to bring session to the other node when one
fails?
When looking at every resources available in the GUI, we can find a Resource
Agent called "stateful", can we use this one to carry sessions over a fail?
If yes, is there any tutorial explaining how to?
I also thought it might be possible to share session data on a DRBD storage
system, I read it is not possible for iptables but would it be feasible with
sshd? I know I already asked this question in another thread but I get no
answer...
for iptables look into the conntrackd daemon and tools, those would be what you
would use to syncronise the connection table from one firewall to the other.
what do you mean when you say you need to manage ssh sessions? if you mean they
go through the firewall, then the iptables stuff should fix this. if you mean
that people connect to the firewall itself and you want the ssh session to
failover to the backup, that's not possible.
